Do oak leaves need to be cut up because of the waxy coating they have?
Ian Blake
42:53
will newspapers add acidity to the compost?
Chelsey Hahn (she, her, hers) - CT DEEP
45:23
Just a reminder - Dawn will answer your questions at the end of her slides, thanks for these great questions thus far.

Can wood stove ashes be composted?
Maybeth Morales-Davis
47:30
How often do you turn the pile?
Robert Rafka, Speaker
47:39
Wood ashes shouldn't go in...I'll cover this in my talk
Robert Rafka, Speaker
49:16
Oak leaves can go in a pile...shredding helps break down the waxy cuticle
Kathy Engle-Dulac
49:36
Thank you!
Robert Rafka, Speaker
49:57
Newspapers decompose pretty much like any other strean...no significant effect on pH
Cynthia Rabinowitz
57:06
I get potato scab on some varieties but I just ignore it and generally just peel the affected potatoes and the inside is usually just fine
Liz Moyse
58:34
Can you inadvertently add diseases to the pile if you put in potato peals that are decomposing (i.e., bad potato)? In other words, do you need to be careful about what type of veggie waste you put in compost?
Robert Rafka, Speaker
01:00:06
Yes, but many of those disease organisms are endemic in the environment anyway
Liz Moyse
01:02:21
Thx!
Moira Snover
01:02:43
What can we do during the winter months when the temperatures are low and the pile doesn’t heat up?
Robert Rafka, Speaker
01:03:42
Insulation helps as does a higher ratio of nitrogen to carbon in the incoming stream
Dan Gallagher
01:04:33
Monique Bosch from Wiggle Room in Bridgeport is in the house and in my opinion an excellent source of Composting Worms
Robert Rafka, Speaker
01:04:54
A larger pile also helps because it has a lower ratio of surface area to volume...less heat loss.
Steve Seltzer
01:05:15
I have pigs, turkeys, goats and turkeys. So far I have a big pile of pig manure mixed with straw bedding. What is the C:N ratio of this pile?
Robert Rafka, Speaker
01:06:06
Depends on how much bedding. The manure alone is quite high in urea and uric acid
Abdellatif Bouchane
01:07:30
is there a relation between the adjustment of the c/N ratio and the quantities of waste to be used?
Steve Seltzer
01:07:33
Probably 50 times as much manure by volume as straw bedding
Kathy Engle-Dulac
01:07:59
I hope they offer the master composter class again soon!

Is charred wood (from a fireplace) a source of carbon?
Robert Rafka, Speaker
01:10:42
Charcoal in powdered form is a form of biochar, but not a typical source of carbon (organic)

01:14:55
is compost really effective against crop diseases ?
Steve Seltzer
01:16:05
Our pile of mostly swine manure is a small windrow, 4 feet tall, 20 feet wide, 6 feet deep. it is at about 135 degrees
Robert Rafka, Speaker
01:16:13
Somewhat and it can be considered to be part of a IPM system
Steve Seltzer
01:22:39
If swine manure is 14:1 and straw is 80:1 c/n, how do I achieve proportion of 25-35:1 c/n?

On Farm Composting Handbook NRAES-54. This is the original publication - there's now a newer version - but this is a great resource. https://campus.extension.org/pluginfile.php/48384/course/section/7167/NRAES%20FarmCompost%20manual%201992.pdf
Robert Rafka, Speaker
01:24:08
About 4:1 v/v straw to manure would get you in range
Steve Seltzer
01:24:37
Thank you Robert.

Kara Donahue
01:40:10
I assume composting kills any insect cocoons so are you leaving some leaves for them to overwinter and others that you compost?
Lauren Little
01:40:38
What about composting
Joan Haddon
01:41:16
What about Newspaper and paper ink. Is it OK
Lauren Little

If you have questions for Dr. Rafka, please put them here in the Chat Box.
Abdellatif Bouchane
02:11:19
are there any natural products that can be added to the compost to promote the activity of microorganisms or natural enzymes for the degradation of complex molecules
Abdellatif Bouchane
02:24:40
can we use cedar in compost ?
Heather Palardy
02:25:04
How about Pine needles?
Sherill Baldwin she/her CT DEEP
02:49:53
From Peter Moon: Dr. Rafka, time-temperature pathogen destruction criteria for biosolids is 55 degrees (C) or 131 degrees (F) for 72 hours. The composting industry generally extend these same criteria to most other feedstocks. However, you indicated pile temperatures of 160 to 170 degrees (F) for livestock manure but with no time component. Can you clarify?

You seem to prefer composting with worms. How do worms change this process; are they preferred?
